There are so many reasons to be afraid of intimacy and love we can hardly begin to enumerate them. John Paul-Sartre opined that lovers want to possess the desire of the other to quell their fear of rejection and abandonment. In that way he believes that all love relationships are doomed to battles for independence and ever present dependency.
I have enormous respect for anyone that goes to therapy and extending that, anyone who walks into my office. To walk into a therapist's office (or in my case, a coach's office) admitting you need help and wanting to change is, in my eyes, admirable. In addition to that, to keep going to therapy is hard.
